rpubchem: An Interface to the PubChem Collection

Access PubChem data (compounds, substance, assays) using R.
Structural information is provided in the form of SMILES strings.
It currently only provides access to a subset of the
precalculated data stored by PubChem. Bio-assay data can be accessed to
obtain descriptions as well as the actual data. It is also possible to search for assay ID's by keyword.
